CAR CONSTRUCTION.

Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed February 8, 1916. Serial No. 76,898.

To all whom it may concern:

Be it known that we, FELIX Koorr, a citizen of the United States, and ALFRED K. PEHRSON, a subject of the King of Sweden, residing at No. 62 North Harrison Ave, Bellevue, and No. 1519 Davis Ave, N. S., Pittsburgh, respectively, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Car Construction of which the following is a specification.

An object of the invention is to provide a car having side posts which extend for substantially the full height of the side walls, and which at their lower ends are bifurcated and spread apart to form diagonal braces which may be secured to the side sill or bottom chord of the side wall.

Another object of the invention is to provide a car having side posts .which are slit at their lower ends, the portions resulting from such slitting being spaced apart to increase-the width of the lower ends of said posts.

A further object of the invention is to providea novel letter board and top plate constructiom'and a still further object of the invention is to provide a novel construction between the side posts of the car and the combined, letter board and top plate.

With the above and other objects in view, the invention resides in the construction, arrangements and combinations of parts hereinafter described and claimed.

Referring now to the drawings, in which like reference characters refer to like parts, Figure 1 is a side elevational view of a'portion of a car embodying the invention, portions of the side sheathing being broken away; Fig. 2 is a sectional view of the same taken on the line 22 of Fig. 1. Fig. 3 is an enlarged sectional view taken on the line 33 of Fig. 1; Fig. dis a side elevational view of'a portion of the car showing a modification; Fig. 5 is a sectional view taken on I the line 55 of Fig. 4:; Fig. 6 is an enlarged sectional view taken onthe line 66 of Fig. 4, and Fig. 7 is a side elevational view of a portion of the car showing a modification of the invention.

Referring now in detail to the drawings, 1' indicates the side sill or bottom chord of the side wall, 2 the combined letter board and top plate or top chord of the side wall and 3 the side posts, whichposts at their lower end portions are connected with the side sills 1, and at theirupper end portions with the combined letter board and top plate 2.

Each of the posts3 comprisesanumber of U orchannel section having a Web 4 and flanges 5, 5 projecting inwardly therefrom, such flanges being bent at an angle to form flanges 6, 6, which flanges 6, 6 strengthen the web, and for a portion of their length are adapted to form portions of a Window frame. The lower end portion of the web 1 is slit in the direction of the length of the post and the resulting portions 7 and"8 are spread apart, and secured to the bottom chord 2, thus forming a wide'base for the post and also forming integral diagonal braces which are substantially of Z shape in cross section.

9 indicates the lower sheathing plates of the side wall which are secured to the side posts 3 below the windows and to the side sills 2. 10 indicates a belt rail'which may be secured to the sheathing plates 9 and to the posts-3. It will be understood that in some constructions this belt rail may be. omitted.

'The combination letter board and top plate, or topchord of'the side wall, comprises a plurality of members 11, each of which is provided with avertically disposed web 12 and top and bottom horizontally disposed flanges 13 and 14 respectively, the inner edge portion of the flange 14: being bent downwardly to 'form a "flange 15 which strengthens the'member, and may also form a portion of the window frame. To further strengthen the member 11 the web 12 is preferably provided with a corrugation '16 which may extend for substantially the full length of the member. Each of these members 11 overlaps adjacent posts and is secured to the webs 4 by rivets or other suitable means. It will be noted that each of'the posts 3 is slightly effect at its upper'end portion so that when the member 11 is secured to the post the outer surface 17 of the flange 1d will be in the same vertical plane as the outer surface 18 of the flange 5 of the post 3. It will further be noted that if desired the post 3 may be offset in a direction-transversely of the car and'that the end portions of the combined letter board and top plate maybe secured to the'post so that theouter surface of such letter board will be in the same vertical plane as the outer surface of the lower portion of the post.

To further strengthen the posts 3, and to form a strut therefor, members 19, preferably of channel form, may be provided which extend upwardly from and are connected with the bottom chord 1, through the medium. of a transverse member 31 of the under-frame and the gusset plate 32, and for a portion of their length may be secured to the web a of the post. Above the posts these members may be extended across the car to form carlines for the support of the usual. roof sheets.

In l, 5 and 6 a modified top chord 2 has been illustrated, each member 11 of which, instead of overlapping adjacent posts, is provided with end flanges 20 which may be secured to the flanges 5 of the posts.

111 Fig. 7 a modified construction has been illustrated which comprises a bottom chord 21, a top chord 22 and a post interposed. between and connected to such chords. Each of the posts comprises a member of U or channel section having a web 2i and flanges 25, projecting inwardly therefrom, which flanges at the upper end portion of the post are preferably bent outwardly and are cured to the top chord 22. lhe lower end portion of the web 2% is slit in the direction of the length of the post and the remaining portions 26 and 27 are spread apart and are secured to the bottom chord 21, thus forming a wide base for the post and also forming integral diagonal braces which are substantially of angle shape in cross section. To further strengthen the post a strut member 28 may be provided which at its upper end may be secured to the portions 26 and 27 of the post and at .its lower end. to the bottom chord 21. 29 indicates the letter board which may comprise a plurality of members 30, which are secured throughout their length to the top chord 22 and at their ends are secured to the posts 23.

The foregoing description has been limited to a passenger-car, but it will be understood that if desired the invention may be used in connection with freight cars.
